@Description(name = "from_unixtime",
- value = "_FUNC_(unix_time, format) - returns unix_time in the specified
format",
+ value = "_FUNC_(unix_time_in_seconds, format) - returns unix_time in the
specified format",
Review comment:
It seems, this change and example would bring in change in DESC FUNCTION
output. Can we keep it same as base code?
